Should I Supplement Selenium? Selenium is not included in our free choice kits; however, we do carry Selenium supplements which can be purchased separately and offered if needed. While many soils are Selenium deficient, some may have excessive amounts of selenium. Visit this link to find out if you are in a Selenium deficient area. You may also consult your local vet or request a blood test.

Our Free Choice minerals are also available in kits - See the Kits section.
